The Market's 10 Worst Stocks

What were the 10 best stocks of the past 10 years, and what could we learn from them? Those were the questions we asked a few months back, and we discovered that the 10 best stocks of the past 10 years were:

Obscure.

Ignored.

Small.

That's all well and good, but then we got to thinking: What were the 10 worst stocks, and what could we learn from them?

Danger! Danger!There are a few caveats. First, these companies are all still in business and trading on a major U.S. exchange. Many publicly traded companies went bankrupt over the past decade, leaving shareholders with nothing. We also excluded companies that did not have a market cap of more than $200 million 10 years ago, to keep penny stocks out of our results.

Those qualifications aside, here's what we can conclude: The 10 worst stocks of the past 10 years were also small. And that makes sense: Small companies offer the greatest risk and greatest reward in the market.

Be boring, be rationalBut none of these stocks could be called obscure or ignored. While the 10 best had boring names such as Hansen Natural and Pool Corp., the 10 worst had exciting names -- like Genelabs Technologies and Gilat Satellite Networks -- that conjure up images of the next great technological or pharmaceutical breakthrough.

Many investors believe that buying into these breakthroughs is the key to thumping the market (and consequently, they value them above and beyond justification). Yet that's just not the case. As Paul Elliott noted recently, the risk with small caps may not be with the companies, but with us investors! That's because too many of us go chasing after the next big thing rather than systematically searching out and finding legitimate small businesses with strong fundamentals trading at reasonable prices.

Foolish conclusionThe 10 best and 10 worst stocks of the past decade were small caps. But they were very different kinds of small caps.
